No problem, let's work through this together. We're starting with 1362 and 8021 and adding them all up.

Step 1: We'll start by adding the digits 2 & 1 in column 1 and get 3.

Step 2: We'll start by adding the digits 6 & 2 in column 2 and get 8.

Step 3: We'll start by adding the digits 3 & 0 in column 3 and get 3.

Step 4: We'll start by adding the digits 1 & 8 in column 4 and get 9.

So, 1362 + 8021 = 9383.
